Runtime error when I close 17.1.1

Every time I close Lectora 17.1.1, I get a runtime error from the Microsoft Visual C++ Library saying, "R6025 - pure virtual function call." That's followed by a message from Windows saying Lectora has stopped responding.

Microsoft says this is a programming error. It's only annoying and doesn't seem to cause any problems, but it is annoying.
